mounted a conveyer drum -15, adaptedto' be rotated in a step-by-stepmovement by im; proved-operating mechanism 16. v

Thehousing 14 is preferably made in three sections including acentralcasing 17 and apai-r of side Wall sections 18 and 1-9. EX-tending through the base of the casingl'i;

are screws 20 for securing ,the housing to a supportingplate 21 mountedon a bracket 22 1 which is secured to thecultivator beam as illustratedin Fig. 1. a

Formedin the casing 17 cated cylindricah opening- 23 in which theconveyer drum located. Formed in the top andbottoniofthe casing, is aninlet open ing 24: and an outlet 25* communicating; respectively, withthe magazine 11 and chute 12.

the construction illustrated, the side Wall sections 18 and19aremountedon the supporting plate 21 and the upper-faces thereof areprovided with arcuate le dges Zii for supporting themagazine l1. Formedin thejinnerfaces of the sectionslg and 119, are recesses 27, in vvhichare seatedthe ends ofa-shaft'28, upon which the drum 15 is rotatis acentrally loably mounted. The side sections 18 and 19 are secured to theshaft 28 by screws 29.

The conveyer drum 15 comprises a spider 30, rotatably mounted on theshaft 28 and having a rim 31 provided with a plurality of pockets 32,each of which is adapted to carry a charge of seeds from the opening 24to the opening 25.

Fixed on one side of the spider 30, is a ratchet 33 which is restrainedagainst backward movement by a detent 34 mounted on the casing part 17.The ratchet 33 is rotated step-by-step by the improved operatingmechanism 16.

The magazine 11 is provided with a removable lid 35 and a bottom 36,which is inclined adjacent an outlet opening 37.

Formed in the bottom member 36, is a re cess 38 in which is located ashoe 39 pivotaliy secured to a pin 40. Due end of the shoe 39 is adaptedto ride on the rim 31 of the conveyer drum to level the seeds in thepockets 32. The shoe 39 is yieldingly urged into engagement with thedrum by a spring 41 bearing between the opposite end of the shoe and thetop of the casing 17.

The magazine is hinged at one side to a pin 42 mounted on the casing 17.Mounted on the opposite side of the magazine, is a bolt 43 for engagingan eyelet 44 on the casin 17,

In the form shown, the operating mechanism 16 includes a manuallyoperable lever arm 45, having its lower end pivotally connected to thesupporting plate 21 by a pin 46. The lever 45 is slidable between a pairof guide rails 47 and 48 secured to the casing 17 and support 21.

Pivotally mounted on the lever 45, is a pawl 49 extending through a slot50 in the casing 17 for engagement with the ratchet 33 of the conveyerdrum. The pawl 49 is normally urged downwardly into position to en a ethe ratchet b means of a s rin D b i D 51, which is mounted on the upperedge of the pawl and which bears against the upper edge of the slot 50.

The lever 45 is normally held in a retracted position by a spring 52mounted on the base plate 21 and extending through a guide 53 on thelever 45.

In the form shown the chute 12 is secured to the lower face of thesupport 21 and com municates at its upper end with the opening 25through an opening 54 in the support 21. Mounted in the lower end of thechute 12, is a gate 55 adapted to temporarily support a charge of seedspreparatory to its ejection.

The gate 55 is hinged on a pin 56 and has an arm 57 pivotally secured tothe lower end of a link 58 extending upwardly within the chute.

The upper end of the link 58 is pivotally secured to a bell crank 59,secured to the easing 17 by a pivot pin 60. The upper end of the bellcrank 59 engages a rotary cam 61,

which is fixed on the spider 3O opposite the ratchet 33. The cam 61'rotates step-by-stcp with the drum 15 under the action of the lever 45for rocking the bell crank 59 and thereby forcing the link 58 downwardlyto open the gate 55.

Mounted in the upper end of the chute 12, is a spring 62 engaging thelower end of the bell crank 59 for raising the link 58 to normally closethe gate 55.

In the form shown the spout 13 is located directly behind one of thecultivator shovels 3, so as to be adapted to deposit the Seeds in thefurrow made by the blade 4. In order to avoid injury to the spout, inthe event the wooden peg 9 is sheared, the spout is hinged to the chute12 by a hinge 63.

Mounted on the front part of the spout 13, is a guide rail 64, whichengages a link member 65 rigidly secured to the shovel bracket 5 fornormally holding the spout in a forwardly inclined position as shown inFig. 2. i

In operation, the riding cultivator is operated in the usual manner, soas to straddle the row of corn. When the operator sees that the seeds inany hill have not sprouted, at the moment the foremost shovel approachesthe barren hill, the lever 45 is shifted forwardly to move the conveyerdrum one step and simultaneously open the gate 55. The seeds in thechute 12 thereupon drop through the spout 13 into the furrow behind thecultivator shovel.

Upon each movement of the conveyer drum, a charge of seeds is taken fromthe magazine 11 and another charge is dropped into the chute 12 toreplace the charge ejected through the spout 13.

Although but one specific embodiment of this invention has been hereinshown and described, it will be understood that details of theconstruction shown may be altered or omitted without departing from thespirit of this invention as defined by the following claims.
